The Bears have a right tackle problem. Could Kyle Long be the solution?

Less than two weeks before the season begins, the Bears are still searching for stability at right tackle.

Charles Leno, a 2014 seventh-round pick, has struggled during his two preseason starts at the position. Leno's promotion to the first string came only after Jordan Mills' play was marred by inconsistency during training camp and into the first exhibition game against the Dolphins.

More consistency will be needed up front. So the possibility of shifting right guard Kyle Long to right tackle remains under consideration at Halas Hall.

To do so, any potential move of Long to tackle would require Vladimir Ducasse to assume a starting role at right guard.

Coach John Fox was asked after Monday's practice at Halas Hall what he will be looking for at right tackle over the next week and a half to feel more comfortable with that position.

"We'll end up with whoever ends up proving they're worthy," Fox said. "I don't know that you ever really get comfortable because you know it's very fluid. And it's been like that every season I've been in the league."

Long saw time at right tackle during portions of organized team activities and minicamp earlier this year. But since training camp opened in late July, he has practiced primarily at right guard, the position at which he has made all 31 of his career starts.

Moving on:Ryan Mundy's playing days with the Bears are likely over. The 30-year-old safety was placed on injured reserve Sunday with a hip injury. And when his two-year contract expires in March, he doesn't figure to be in the team's future plans. Mundy started 16 games in 2014 and tied for the team lead with four interceptions.
